At the front side, there are two adaptors available. One is for you to use a normal 1.25" eyepiece. The other has a T/T2 male thread that could be connected to a T/T2 adaptor.
The ability to get it connect to a T/T2 adaptor is important if you want to take picture by your SLR or DSLR cameras as it is a more secured connection.
It is a manual wheel and is made of high grade Al-alloy with excellent finishing.
The filter wheel has a T/T2 adaptor which can be connected to any T/T2 adaptors
The 1.25inch 5-position filter wheel requires a light touch to revolve the wheel into its next position with minimal disruption to your scope settings.
